Abstract: PROBLEM TO BE SOLVED: To reduce a leakage of an FET channel by diffusing potassium along an ONO layer backing a trench on the surface of a wafer and forming a gate oxide on the exposed wafer surface. SOLUTION: A trench 120 is etched in a wafer 122 through a pad stack 121, a channel, a source, and a drain are formed in an FET region 124 defined above, and an ONO layer 126 backs the trench 120, passes through the surface 128 of the wafer 122 and extends on both sides of each trench 120 along the pad stack 121. An N<+> polysilicon layer 130 is deposited on the ONO layer 126 and is removed so that polysilicon 132 is remained only in the trench 120, and the polysilicon layer 126 is polished to remove the residual ONO layer 124 from the pad stack 121.

IPC: G01N3/04
Filed: 1989-08-28
Abstract: PURPOSE:To form a simple shape for the test piece of hard and BRITTLE material, to provide the test piece at a low cost and to make it possible to perform the highly accurate test by constituting a chuck part with a test-piece holding chuck and a chuck ring. CONSTITUTION:A chuck spacer 2 is coupled at both ends of a test piece 1 and further coupled into a chuck 3. Under this state, a chuck ring 4 is pushed into an inner flange 6. Then, the chuck 3 is tightened by the action of a taper 3a. The spacer 2 is deformed, and the test piece 1 is tightened. Since the gradient of the taper 3a is gentle, the large tightening force can be obtained by the slight pushing force. The test piece 1 is held with frictional force. The test piece 1 and the chuck 3 which are assembled in this way are attached to the flange 6 of a bending-moment removing jig B with bolts 5. Therefore, the jig B can be left alone in the attached state to a testing machine, and it is not necessary to disassemble each time when the test piece 1 is attached. When a high temperature furnace 17 is provided at the central part of a chuck part A, the uniform temperature distribution is obtained along the entire test piece 1. Thus the highly accurate, high temperature test can be performed.
